    African Forests, Threatened, but Resilient

    Forests and climate change are fundamentally interrelated.  Forests play a role in mitigating climate change by trapping and storing carbon in their trees.  Currently, the world’s forests and forest soils store more than one trillion tons of carbon – twice the amount in the atmosphere. The African continent is home to 30% of the world’s…
